Euglycemia
12
Hyperglycemia
13
NHANES prevalence 2015: 49%-52% in the US now pre-diabetic or diabetic UCLA 2016: 55% of Californians are pre- diabetic or diabetic Kraft would predict that many more have hyperinsulinemia Predicting population risk Menke A, et al. JAMA. 2015;314(10):1021-1029. doi:10.1001/jama.2015.10029. healthpolicy.ucla.edu/publications/search/pages/detail.aspx?PubID=1472

Diabetes Paradox? Despite more diabetes & obesity there’s less heart disease Morbidity & mortally not to be confused with incidence and prevalence Diabetes Care March 2003 vol. 26 no. 3 905-910 doi: 10.2337/diacare.26.3.905
15
Atherosclerosis is a metabolic disease Missing pre-diabetes and diabetes also misses cardiovascular disease Dr. Kraft on CV risk
16
Gerald M. Reaven, MD Diabetes December 1988 vol. 37 no. 12 1595-1607 doi: 10.2337/diab.37.12.1595. Slide curtesy lipidsonline.org
18
Lipids, Smoking, HTN, Diabetes Guidelines, risk calculators Lowering cholesterol Diabetes risk buried Framingham Distraction
19
Hyperlipidemia requires remedy Mechanisms remains elusive Diet-heart hypothesis unproven Statins provide small benefit Lipid Lowering Therapy
20
Get with the Guidelines 2009 Towards a Paradigm Shift in Cholesterol Treatment 2015 Debunking the Lipid Hypothesis
21
Mark A. Creager et al. Circulation. 2003;108:1527-1532 Hyperinsulinemia and blood vessel damage
22
Framingham risk calculators: CV risk increased 2-3 fold (middle risk population) Diabetes alone: CV risk increased 6-8 fold Framingham vs. Diabetes Risk Circulation. 2002; 105: e132-e137 doi: 10.1161/01.CIR.0000013953.41667.09
23
Atherosclerosis is a symptom of diabetes Focus insulin excess, IR, and inflammation Many at risk are missed Diet and lifestyle, not medicine It’s the Insulin Stupid!
24
Low carb best Eliminating processed food Eating less Movement & activity Smoking cessation Proper sleep & happiness Diet and Lifestyle
25
Early level of suspicion FBG & HbA1c - are poor screening tools alone 2 hr OGTT including 1hr glucose <155 mg/dl (8.6 mmol/l) Insulin - fasting, 5hr assay, 2hr <30 uIU/ml Inflammatory markers, lipid quality, etc… Clinical assessment doi: http://dx.doi.org/10.1210/jc.2015-2573
